TYPE-WRITING MACHINE.

SPECIFICATION forming part of Letters Patent No. 315,700, dated April 14, 1885. Application filed March 13, 1884. (K0 model.)

To all whom it may concern:

Be it known that I, EDWIN S. Barman, a citizen of the United States, residing in the city and county of San Francisco, and State of California, have invented certain new and useful Improvements in Type-Writing Machines, of which the following is a specification.

' My invention relates to improvements in type-writingmachines in which a paper-carrying roller is moved from right to left above an inked ribbon, while the types mounted upon levers operated by keys placed in banks produce the desired impressions upon the paper.

In the typewriting machines of the character as usually constructed the carriage or paper-carrying roller is conveyed to the left by a spirally-coiled spring beneath the body of the machine, and when it reaches the end of each printed line it is necessary for the oper ator to lift the lever and revolve the roller up on which the paper rests the distance between the lines, and then push it to the right to the commencement of the next line.

The object of my invent-ion is to provide a means whereby these movements may be performed in an automatic manner, relieving the operator from the necessity of performing this oft-recurring task. These objects I accomplish by the means illustrated in the accompanying drawings, forming apartofthis specification, and in which- Figure 1 is a perspective view showing my improvements applied to a type-writer or caligraph, yet I have not deemed it necessary to illustrate a complete type-writer or cali graph but only so much of one as will serve to illustrate the application of my improvements. Fig. 2- is a perspective view of one end of the reciprocating roller and papercarrying frame. Fig. 3 is an end view of the same. Fig. 4 is a front view of the movable frame partly broken away. Fig. 5 is atop View of the roller-turning device. Fig. 6 is a sectional side elevation of the carrier-reeiprocating mechanism, showing the position of the parts when the type-writer is about to be operated and the carriage is at the lefthand side of the machine. Fig. 7 is the same view, but showing the position of the parts when the carriage has completed its travel and is ready to be returned to its original position.

Similar letters of reference are used to indicate like parts throughout the several figures.

A represents the supporting frame-work of the form of type-writing machine known as the caligraph, and B the carriage carrying the impression cylinder or roller 0. This paper-carriage is supported in the usual manner upon the guides D and E, and is carried forward or along the guide-rails by the action of the spring-rod F, pulling against the said carriage, which is held in the set position by ratchetbars G G and pawl H, which lets go every time a key is struck and catches again, and in the interval the action of the coiled springrod F and its connecting levers and rods, to be hereinafter described, pulls the carriage and paper along the space of one letter. Therear end of the spring-rod F is carried through the frame of the machine, and upon its squared end is placed a vibrating leverrod, I, the upper end being provided with a connecting-rod, J, extending to the pin Kupon the outer or slip ratchet bar, G, as shown in Fig. 1, and as the pawl H. attached to the rod H, which is moved in the usual manner, is thrown into and out of contact with the slip and the fixed ratchetbars the carriage is moved forward along the guides and the letters and words are printed. When the end of a printed line is reached, the operator lifts the carriage or tilts it upward upon the rear hinges, L L, and revolves the paper-carrying roller the space of one line and forces the carriage backward to the point of commencement.

The devices as heretofore constructed for producing and carrying out these last-named movements have required much attention, time, and labor of the operator. Hence the object of my invention is to proy ide an improved mechanism for returning the carriage and partially rotating the roller for the purpose of obtaining line-space in an automatic manner.

Upon one side of the machine is placed an automatic carriage-returning mechanism, such as is illustrated in Figs. 1, 6, and 7, which consists of a supporting frame-work, a, carrying upon the shaft ba loosely-journaled ratch- Lil et-wheel, ,0, having upon its side a. pawl, d, engaging with the ratchetwheel (2, which forms one of the heads of the winding-drum], keyed upon the shaft 1). 7

Upon a shaft, 9, placed near the lower edge of the frame a, I pivot a pawl, h, which en gageswiththe teeth of the loose ratchet wheel 0,.

Near one end of the shaft 70, and in such a position thatit will come outside the head of the winding-drum, I key the lever m, carrying upon its side near the lower end a stop, a, which engages with the teeth of the ratchetwheelc. To the upper end of this lever I pivot a plate, 0, having several holes for the purpose of adjustment, and to this plate in turn is pivoted a head, p, which receives the screw-threaded end of the connecting-rod g,

which is connected with a similar head, 1', at-

tached to an adjustable plate, 8, pivoted to the clamp t, adj ustably secured upon the vibrating lever-arm I, whichv connects with the movable carriage of the caligraph, as clearly shown in Fig. 1.

The operation of this mechanism will be hereinafter more fully described.

The device for automatically turning or producing a partial revolution of the paper-carrying roller to obtain line-space is illustrated in Fig. 2.

To the end of the paper-carrying roller is fixed the usual gear-wheel, a, made rigid with the said roller and held in position by a catch or lug, 12, upon the arm 0, pivoted to one end of the carriage-frame, as shown at d, and held down in position by a retractive spring, 6.

f is an end bar, which is pivoted at the point d, and extends to the front of the paper-carrying roller, where it receives a stay-rod, g, t

extending across the front of the roller to the opposite end,where it enters a similar end bar. This stay-rod forms the axis of avibrating lever, h, the upper end of which is provided with a hinged or pivoted pawl, i, which engages with the teeth of the gear-wheel a.

Upon the face of the end bar, f, I bolt the lug j, which carries a downwardly-extending pin, k, upon which is secured in such a manner as to be capable of a partial revolution the collar Z, carrying at its upper end an upwardly-curved lug, m, which, by engaging or coming in contact with the end bar, f, limits the rotation of the collar. To the lower end of this collar is attached the horizontally-vibrating lever a, the inner end of which presses against the lower end of the vibrating lever h, whilethe outer end is provided withasmall pivoted lug, 0, the rear end of which receives the pressure of a fiat spring, 0, which keeps the lug standing outward at right angles to the lever-arm, and forming a head to strike against a stop,-to be presently described.

The object in making the lug'pivotal is to obtain adjustment of the line-spacing.

Upon the end of the frame A, I attach by a set-screw, a", the stop q,having a central slot, 8, for the purpose of adjustment, and an up wardly-curved portion against which the'lug 0' strikes when the carriage is brought back to commence a new line ofwriting or printing.

The operation of my improved carriage-re, turning and roller-turning device will be as follows, to wit: A suitable cord provided with a heavy weightis attached to the winding-drum f, and the cord is wound upon the drum in any well-known manner, either by a key ap plied to the squared end of the drum-shaft or' by a Chinese Windlass. When the cord and weight is wound up, the automatic carriagereturning mechanism will occupy the position shown in Fig. 7. As the letters are struck off or printed, the carriage will move toward the left-hand side of the frame, and in so doing will draw toward the typewriter the upper end of the lever m, which movement will causethe point of the cam Z to gradually rise and liftup the outer end of the extension j of the pawl h, which will be as gradually released from contact with a tooth upon the ratchet-wheel 0. By this time the parts will be in the position shown in Fig. 6, the stop n on the lever mbeing in close contact with the tooth preceding the one held by the pawl h. When, however, the pawl h is released from contact with the ratchet, the drum f will commence to make a revolution or unwind, and will force back the lever m to its original position, as shown in Fig. 7. As this backward movement of the rockshaft takes place the gravity of the long arm j and'the expansion of the spring i will force the pawl h upward, when it will be engaged by the succeeding ratchet-tooth, and the further revolution of thevdrum will be stopped. As the lever m is forced backward by the unwinding of the drum the carrier of the type-writer (to which it is connected by'the rods and levers hereinbefore described) will likewise be carried back along its guide-rails to the point of commencement for the next line of writing or printing, and so this part of the operation may be repeated from time to time until the weight and cord of the winding-drum has run down, when it will be necessary to wind the same up again. As the carriage approaches the place of its original position the projecting lug 0', upon the pivoted lever n, will strike against the upwardly-curved flange of the stop q and be thrown backward, whicha partial revolution of the paper-carrying roller 0. hen the backward movement of the roller has been completed, a spring, suitably connected to the upper end of the vibrating lever,-draws the same back to its original position, ready for the next movement.

Having thus described my invention, What I claim, and desire to secure by Letters Patent, is-
